东北亚巨石文化起源:朝鲜半岛南部支石墓释光年龄证据

Evaluation of origin of Northeastern Asian megalith culture: Evidence from luminescence dating of dolmens from the Korean Peninsula

采用热释光和红外光释光测年技术获取了采自朝鲜半岛西南部和顺支石墓遗址剖面中的陶片和沉积物的年龄。古陶片的热释光年龄分别是(3100±210)a和(3680±320)a,相应文化层中支石墓墓葬层位的红外光释光年龄分别是(2200±190)a和(2900±310)a。古陶片的热释光年龄老于地层的红外光释光年龄,代表着支石墓墓葬的下限年龄,和顺遗址的支石墓墓葬年龄不应该老于(3680±320)a,而相应文化层红外光释光年龄应该代表支石墓墓葬的上限年龄,和顺遗址的支石墓墓葬年龄不应该比(2200±190)a年轻。古陶片的热释光年龄与文化层及相关层位的红外光释光年龄数据,指示以支石墓为代表的东北亚巨石文化在朝鲜半岛南部可能兴起于当地的青铜器时代中期。

Thermoluminescence （TL） dating of fragments of pottery and infrared stimulated luminescence （IRSL） dating of sediments from cultural layers at Hwasun dolmen sites in the southern Korean Peninsula, are obtained in this paper. Two pottery TL ages are （3100±210） a and （3680±320） a, while two related sediment IRSL ages are （2200±190） a and （2900±310） a. TL ages of pottery are generally greater than those of associated sediments, and may represent the bottom limit of the dolmens’ age at Hwasun, e.g. （3680±320） a. The IRSL ages of sediments from cultural layers give the upper limit age of the Hwasun dolmen sites （2200±190） a. Both TL and IRSL ages indicate that northeastern Asian megalith culture might have arrived at the southern Korean Peninsula during the local Bronze Age.
